This will not create anymore problem unlike you will try to do some strenuous activity. Another thing you could do is stay indoor most of the time.
What is Fluorescent Lighting
Understanding how fluorescent light tubes work begins with a basic understanding of how light is produced. The basic unit of light is the light photon, which is released by an atom when its electrons become energized. As you may know, electrons are negatively charged particles that orbit around an atom's positively charged nucleus.
Global warming article
The analysis of data shows that during last century our planet the Earth was warmed up on one degree above an average indicators . Scientists presumption of fact - in the next 50 years the temperature will rise for 3-5 degrees and that will lead to heavy consequences both for the Earth, and for people , flora and fauna.
Scientists ideas on rescue the Earth from global warming
In 1827 the French physicist Joseph Fourier has assumed that the atmosphere of the ground carries out function some kind of glasses in a hothouse: air passes solar heat, not giving it to evaporate back in space. And it was right. Scientific proposals for dispose a problem of global warming have at times fantastic character, but are considered by experts seriously because can appear useful, sooner or later.
Zambia Enacts Law to Regulate Genetically Modified Organisms
Zambia now has a biosafety law. The country's parliament adopted the law, last week. The law will regulate genetically modified organisms (GMOs) in the country. This is good news as Zambia, now, stands to gain from modern
Humans have something in common - DNA (Deoxyribonucleic Acid) which is secretively hidden in our chromosomes. Since DNA is a type of nucleic acids which is made of from millions of nucleotides. Nucleotide is a basic unit of building a long strand of DNA - just like building a house; the basic units are the bricks, concretes and etc.
What is so mysterious about DNA
Since it's a small structure with approximately 2.2 - 2.6 nanometers wide, it contains a genetic code that can be deciphered to unveiled the secrets of our body. Advances in DNA technology enable us to unlock the secrets of our body as to search for the meaning of mankind.
You look like your mom...you'd got the eyes just like your father...you're as strong as your uncle...
These traits can be explained as it is related to genes - genetic information that inherited from our parents - possibly contains sub-information about our ancestors. DNA can be treated as our entity - a living proof that makes us adapting to all sorts of surroundings.
This represents how humans are enabling to survive since human population had reached more than 6.6 billion as recorded on July 2007.
How do we look different among each other
All of us differ to the type DNA - means that each of us has DNA which has different genetic information except individual twins who has identical DNA. People often being mislead by assuming fingerprint is similar to DNA.
Actually, humans have their own distinctive fingerprints and DNA but individual twins have different fingerprints. However, differences of DNA among races based on their appearances (phenotypic traits) have yet able to be distinguished as we need more time and effort to map and identify common distinctive traits at the DNA level.
